I treated myself with my first expensive nail polish and I don't regret it even for a second."Knackered" is a metallic purple-green polish with shiny pieces of glitter that gleam in all the colors of a rainbow. This polish is very sheer and not opaque after three coats, you can still see the white of the tips shine through. Usually I don't like sheer polishes but this nail polish is so beautiful that nothing could weak my enthusiasm! Even my boyfriend likes this color and said it looks like 80ies science fiction. ;-)
